IMO, the cruiserweight title will be brought back once WWE's cruiserweight show starts later in the year (or whenever the WWE Network starts up).
However, neither Sandow, nor Mahal are cruiserweights, and Hornswoggle isn't a wrestler.
Cruiserweights are guys that are 220lbs and less. You're looking at guys like Justin Gabriel, Hunico, Sin Cara, Evan Bourne, Trent Barretta, Tyson Kidd, Yoshi Tatsu, Zack Ryder and even guys like Christian, Kofi Kingston, Dolph Ziggler, Cody Rhodes, R-Truth amongst others as the contenders for the title.
Yeh Mate Your Right about Sandow nd Mahal, Good that you didnt put Heath Slator, He should be United States Champion
